(1) Paper Feed from 1st Tray
1. As indicated in Figure 2-1, when the solenoid is ON, the registration motor rotates (CCW),
and transports the paper until IN1 sensor turns ON. (The hopping roller rotates when the
solenoid is ON.)
2. When IN1 sensor is ON, a constant number of sheets are transported against registration
roller L. (This corrects paper skewing.)
3. As indicated in Figure 2-2, the solenoid is turned OFF and paper is fed with registration roller
L. (The registration roller L feeds the paper when the solenoid is OFF.)

(2) Paper Feed from MPT
1. As indicated in Figure 2-3, when the solenoid is OFF, the registration motor rotates (CW)
and continues to transport paper until IN2 sensor turns ON. (The MPT hopping roller drives
the paper until the registration motor rotates in the CW direction.)
2. When IN2 sensor is turned ON, a constant number of sheets are transported against
registration roller U. (This corrects paper skewing.)
3. As indicated in Figure 2-4, the registration motor rotates (CCW), and transports the paper
with registration roller U. (The registration roller U feeds the paper when the registration
motor rotates in the CCW direction.)
